Traction control, what is that? lol. Euro E36's never came with such non-sense. My traction control is my right foot.
the car could be diagnose with an OBD 2 scanner or even a BMW GT1 to erase, code or program the ECU if i need to.

ABS, and all other modules in car could be scan be scanned if there is any fault.

My car is emission except, and even if i were to do emission it will pass if i have cats, the s54 runs and burns much cleaner than the old M52.
